The best and most soil-friendly approach to tackling Japanese knotweed

Japanese knotweed, which originates from Japan, has been a major problem in the Netherlands for decades. The roots of this plant are exceptionally strong and grow through cracks in foundations, pipes, sewers and roads, leading to high repair costs. Furthermore, the plant grows so densely that other plants and flowers are deprived of light and space, resulting in a decline in biodiversity.

The challenge is therefore clear: how do you protect the environment from Japanese knotweed without harming soil life? Is that even possible? 

The solution: DuPont™ Plantex® Platinium

What you need is a solution that is both effective and sustainable. DuPont™ Plantex® Platinium has proven in various projects to effectively and sustainably control Japanese knotweed.

This innovative weed barrier consists of four layers, making it exceptionally strong against this stubborn plant. Moreover, it is the only solution with a gurantee of up to 35 years* that the structure will remain intact. This effectiveness creates a maintenance-free environment. 

For over 20 years, DuPont™ Plantex® solutions have been known for their lack of complaints. At the same time, DuPont™ continues to develop and innovate ensure the highest quality. 

Benefits for soil and the environment 

Covering Japanese knotweed with Plantex® Platinium effectively stops the growth of this invasive plant. At the same time, the soil continues to function as intended, as the fabric allows air, water and nutrients to pass through. This ensures a healthy soil structure and supports a thriving ecosystem, without disrupting natural processes. 

In addition, this solution offers significnt benefits: 

• No use of chemical pesticides 
• Fully recyclable 
• No damage to surrounding plants or soil 

These properties not only help to control Japanese knotweed but also prevents the quality of the living environment. 

Sustainability

The products in the DuPont™ Plantex® collection contain up to 55% post-industrial recycled (PIR) material. These raw materials are sourced from industrial waste generated during the production process. Reusing these materials contributes to a circular economy and reduces waste streams.

The thermally bonded structure of the fabric remains intact, even when cut or trimmed. Polypropylene is naturally non-absorbent and does not leach any substances. Unlike woven fabrics, the material does not fray, meaning no harmful microplastics end up in the soil.
